Todays Trivia: kivy.lang.BuilderException: Parser:

[T500]

Its one of those stupid points of observation that you see from time to time. Its existence is unlikely to influence anything in the whole wide universe... but it does exists :)

Indeed the error below is in line 74 to all known editor programs on my system, yet highlighted >> line 73:

Sorry its not life changing and trivial in the grand scheme of things. But truthfully and honestly, did anyone notice or even care for that matter?

   File "/usr/local/lib/python2.7/site-packages/Kivy-1.4.1-py2.7-linux-x86_64.egg/kivy/lang.py", line 1032, in create_handler
     raise BuilderException(rule.ctx, rule.line, str(e))
 kivy.lang.BuilderException: Parser: File "./scr.kv", line 74:

Sorry, just a little hearted post about those small things that often escape our attention :)

But it is so much fun being one out. Never mind, a patch, it was a very tough assignment... I had forgotten how to generate a diff file :) 

In file: kivy/lang.py

 ...
 name 'of_kansas' is not defined

Sorry, don't have not the foggiest how to do a git patch upload! 

(Do I hear a collective sigh of relief)
